connected with both the body and the fixed end 332 of each
conductive plate type compression spring 33, so as to realize the
electrical connection between the conductive plate type compression
springs 33 and the body.
The mounting process is as described above, and the process of
dismounting the detachable part 20 from the body is similar to the
mounting process, no further explanation here. The electrical
connection between the detachable part 20 and the body is achieved
through the insertion pieces 21, the conductive plate type
compression springs 33 and the circuit board. No connecting wire of
the detachable part 20 is exposed to the outside, so that the
structure of the entire connecting mechanism is simplified.
The connecting mechanism provided in the embodiment of the present
application is further described in detail below.
Referring to FIG. 2 and FIG. 4, the sliding part comprises a
sliding plate 40, a shifting pillar 41 disposed on the sliding
plate 40, and sliding protrusions 42. Specifically, the inner cover
14 of the casing 11 is provided with a shifting hole 15 and sliding
grooves 16 for use with the sliding protrusions 42. The shifting
pillar 41 extends into the shifting hole 15, and the sliding
protrusions 42 are disposed in the sliding grooves 16, so that the
sliding plate 40 and the inner cover 14 are slidably connected.
There are many ways to connect the inner cover 14 with the outer
cover 13. In the embodiment of the present application, one
implementation is that the inner cover 14 and the outer cover 13
are fixed together by ultrasonic welding. The insertion hole 12 is
formed in the outer cover 13. The detachable part 20 can be
connected with the sliding component 30 through the insertion hole
12.
The sliding protrusions 42 and the shifting pillar 41 are disposed
on the side, facing the inner cover 14, of the sliding plate 40.
One implementation is that two sliding protrusions 42 are
symmetrically disposed on both sides of the shifting pillar 41.
Correspondingly, there are two sliding grooves 16, the sliding
protrusions 42 are disposed inside the sliding grooves 16, and the
sliding protrusions 42 can slide in the sliding grooves 16. The
position of the shifting hole 15 corresponds to the position of the
shifting pillar 41. The shifting pillar 41 extends into the
shifting hole 15, and the shifting pillar 41 can slide in the
shifting hole 15. In use, an external force is applied to the
shifting pillar 41 to make the shifting pillar 41 slide in the
shifting hole 15, and the shifting pillar 41 drives the sliding
plate 40, so that the sliding plate 40 slides in the sliding
grooves 16 through the sliding protrusions 42.
Referring to FIG. 3 and FIG. 5, in the embodiment of the present
application, there are two conductive plate type compression
springs 33 for being connected with the positive and negative
electrodes of an electrical signal during electrical connection.
The surface of each conductive plate type compression spring 33 is
plated with metal, for example, the surface of each conductive
plate type compression spring 33 is plated with copper, and copper
plating can make the conductive plate type compression spring 33
more wear-resistant and less prone to rust, and can enhance
conductivity. Each conductive plate type compression spring 33
comprises two parallel expandable wave springs 334. One end of each
expandable wave spring 334 is a fixed end 332, and the other end is
a free end 331. When the free end 331 of each conductive plate type
compression spring 33 is in linkage with the sliding part, the
conductive plate type compression spring 33 provides a restoring
force through the expandable wave springs 334.
Each fixed end 332 is provided with a connecting hole 335 through
which a screw passes to fix the fixed end 332 on the inner cover
14. Specifically, the circuit board comprises a main board and two
conductive terminals. The two conductive terminals of the circuit
board are provided with through holes corresponding to the
connecting holes 335. The inner cover 14 is provided with a
mounting groove, the main board of the circuit board is stuck into
the mounting groove of the inner cover 14, and the two conductive
terminals are connected with the fixed ends 332 of the two
conductive plate type compression springs 33 respectively. The two
conductive terminals are pressed by the conductive plate type
compression springs 33, and the surfaces of the portions, making
contact with the conductive plate type compression springs 33, of
the two conductive terminals of the circuit board are covered with
exposed copper, so that positive and negative signals from the
circuit board can be transmitted to the conductive plate type
compression springs 33. Due to the fact that electric conduction is
realized through direct contact between the conductive plate type
compression springs 33 and the exposed copper on the circuit board,
electrical connection components can be saved and design space can
be reduced. Each screw is connected to the inner cover 14 after
passing through the connecting hole 335 formed in the corresponding
fixed end 332 and the through hole formed in the corresponding
conductive terminal, so that the fixed ends 332 of the conductive
plate type compression springs 33 and the conductive terminals of
the circuit board are fixed.
In order to allow the insertion pieces 21 of earphones to enter the
clamping holes 32 from the access holes 31 more smoothly and avoid
obstruction when the free ends 331 of the conductive plate type
compression springs 33 are in linkage with the sliding part, the
lengthwise direction of the clamping holes 32 in the conductive
connecting ends 333 extending from the free ends 331 is parallel to
the expansion direction of the expandable wave springs 334.
Referring to FIG. 4 and FIG. 5, the sliding plate 40 comprises a
first plate surface and a second plate surface opposite to the
first plate surface. The first plate surface is provided thereon
with the shifting pillar 41 and the sliding protrusions 42. In the
embodiment of the present application, there are two conductive
plate type compression springs 33. In order to prevent contact of
the two conductive plate type compression springs 33 to cause a
short circuit, the second plate surface is provided with a T-shaped
baffle 43, the T-shaped baffle 43 comprises a side plate 431 and a
partition plate 432, the T-shaped baffle 43 divides the second
plate surface into two regions of mirror symmetry, an expandable
wave spring 334 is disposed in each region, the partition plate 432
separates the two parallel expandable wave springs 334, and the
free ends 331 of the two expandable wave springs 334 abut against
the side plate 431.
In specific implementation, when the sliding part slides under the
action of an external force, the free end 331 of each conductive
plate type compression spring 33 is pushed by the side plate 431 to
move, and when the external force disappears, the free end 331 of
each conductive plate type compression spring 33 pushes the side
plate 431 and drives the sliding part to move. Since the two
conductive plate type compression springs 33 are separated by the
partition plate 432, a short circuit between the positive and
negative electrodes does not occur.
Still referring to FIG. 5, in order to ensure that the free ends
331 do not disengage from the side plate 431 during the expansion
and contraction of the conductive plate type compression springs
33, a limiting part 433 is disposed on the side plate 431, the
limiting part 433 is parallel to the second plate surface so as to
form a limiting groove with the side plate 431, and the free ends
331 of the two expandable wave springs 334 are located in the
limiting groove.
Referring to FIG. 2 and FIG. 6, a fixed plate 44 is further
arranged. The fixed plate 44 is connected with the inner cover 14,
and the sliding part and the conductive plate type compression
springs 33 are sandwiched between the fixed plate 44 and the inner
cover 14. The conductive plate type compression springs 33 are
covered with the fixed plate 44 and the fixed plate 44 is fixedly
connected to the inner cover 14 with screws. At the moment, the
sliding part and the conductive plate type compression springs 33
are sandwiched between the fixed plate 44 and the inner cover 14.
The fixed plate 44 can, but is not limited to, be made of a POM
(polyformaldehyde) material. The surface of the POM material is
smooth and wear-resistant, so that the conductive plate type
compression springs 33 can slide smoothly. One implementation is
that the fixed plate 44 is of T type, and comprises a duplex plate
and a single plate. The fixed plate 44 fixes the fixed ends 332 of
the two expandable wave springs 334 to the inner cover 14 through
the duplex plate, and the single plate is located between the two
conductive connecting ends 333 and connected with the inner cover
14.
In the embodiment of the present application, the body comprises,
but is not limited to, a head-mounted display in a head-mounted VR
(Virtual Reality) device/AR (Augmented Reality) device. The
detachable part 20 comprises earphones and/or a microphone.
Specific details will be given below by taking the detachable part
20 as earphones. FIG. 7 is a structural diagram of the detachable
part 20 according to the embodiment of the present application, as
shown in FIG. 7.
The detachable part 20 is earphones comprising receivers 50 and a
support 51. A connecting wire of each receiver 50 stretches into
the support 51 from the bottom end of the support 51, and then is
led out of the top end of the support 51 after penetrating through
the support 51. The insertion pieces 21 are disposed at the top end
of the support 51. The insertion pieces 21 are connected with the
connecting wires. The surface of each insertion piece 21 is plated
with metal, such as copper. Copper plating can make the insertion
pieces 21 more wear-resistant and less prone to rust, and can
enhance conductivity. The earphones are connected with the body
through the insertion pieces 21, and the earphones are electrically
connected with the circuit board through the conductive plate type
compression springs 33. See FIG. 8 for a schematic diagram after
mounting.
The earphones provided in the embodiment of the present application
will be further described in detail below.
Referring to FIG. 2 and FIG. 7, the support 51 comprises a strut
portion 52, connecting portions 53 provided with receiving cavities
and disposed at the ends of the strut portion 52, and sealing
covers 54. The connecting wires penetrate through the strut portion
52 into the receiving cavities of the connecting portions 53. Each
sealing cover 54 is provided with a fixing hole, and the insertion
pieces 21 are mounted in the fixing holes. Each sealing cover 54 is
disposed at an opening of the corresponding connecting portion 53
so as to seal the corresponding receiving cavity. One
implementation is that the insertion pieces 21 and the sealing
covers 54 are integrally connected by means of insert injection
molding, and positive and negative lead wires of the earphones are
welded to the two insertion pieces 21 respectively. A through hole
is formed in the center of each sealing cover 54. The sealing
covers 54 are fixed to the connecting portions 53 by screws.
Moreover, the sealing covers 54 can be rotated relative to the
connecting portions 53 so as to adjust the angle of the earphones
with respect to the casing 11. In order to enable the earphones to
be fixed at the adjusted angle after adjustment, in the embodiment
of the present application, optionally, a plurality of limiting
plates 55 for adjustment are disposed on the cavity wall of the
receiving cavity of each connecting portion 53. After the
connecting portions 53 rotate relative to the sealing covers 54,
the connecting portions 53 can be fixed in the rotated position by
the limiting plates 55 so as to adjust the angle of the earphones
with respect to the casing 11.
Referring to FIG. 7 and FIG. 9, in the embodiment of the present
application, each insertion piece 21 comprises a first clamping
portion 211, a second clamping portion 212, and a third clamping
portion 213 which are coaxially connected. The third clamping
portions 213 are connected with the connecting wires of the
receivers 50. When the earphones are connected with the body
through the insertion pieces 21, the sliding part slides from the
first position to the second position, the access holes 31 are
opposite to the insertion hole 12, and the first clamping portions
211 pass through the insertion hole 12 and the access holes 31, and
the second clamping portions 212 also stretch into the access holes
31 through the insertion hole 12. By withdrawing the external
force, the sliding part slides from the second position to the
first position under the restoring force of the conductive plate
type compression springs 33. At the moment, each insertion piece
makes the first clamping portion 211 pass through the corresponding
access hole 31 and enters the corresponding clamping hole 32
through the second clamping portion 212, and the first clamping
portion 211 and the third clamping portion 213 limit the axial
movement of the insertion piece 21 along the insertion piece 21
within the clamping hole 32. The insertion pieces 21 of the
earphones are in contact with the conductive connecting ends 333.
At the moment, mounting is completed, and the earphones are
electrically connected with the circuit board through the insertion
pieces 21 and the conductive plate type compression springs 33.
It should be noted that when the detachable part 20 is a
microphone, the receivers 50 in the earphones can be changed to a
transmitter. Specifically, the microphone comprises a transmitter
and a support 51. The structures of the microphone and the
earphones are the same except for the structures of the receivers
50 and the transmitter.
In the technical solution provided in embodiment 2 of the present
application, the mounting and dismounting of the detachable part 20
and the body are realized through the operation of the sliding
component 30. The conductive plate type compression springs 33 can
realize both the spring function and the conductive performance,
and the connection of the insertion pieces is realized through the
conductive plate type compression springs 33, including mechanical
connection and electrical connection. No connecting wire of the
detachable part 20 is exposed to the outside, so that the structure
of the entire connecting mechanism is simplified. The insertion
pieces can be used for electrical conduction, and can also be used
for fixing the detachable part 20 on the body, which saves
electrical connection components. The angle of the detachable part
20 can be easily adjusted with respect to the body, so as to
facilitate wearing and adjustment for users.
Embodiment 3
FIG. 10 is an exploded structural diagram of a connecting mechanism
according to embodiment 3 of the present application, FIG. 11 is a
structural diagram of a sliding component 30 according to
embodiment 3 of the present application, and FIG. 12 is a
structural diagram of an outer cover 13 according to embodiment 3
of the present application, as shown in FIG. 1 and FIGS. 10-12.
Embodiment 3 is another implementation of the connecting mechanism
based on embodiment 1. Specifically, the sliding component 30 is
provided with a spring plate 61 with a protruding structure 60. The
casing 11 is provided with a locking groove 62 and a releasing
groove 63. The sliding component 30 slides from the first position
to the second position, and the sliding component 30 drives the
spring plate 61 to stretch into the releasing groove 63 through the
protruding structure 60. The sliding component 30 slides from the
second position to the first position, the sliding component 30
drives the spring plate 61 to stretch into the locking groove 62
through the protruding structure 60, and the movement of the
sliding component 30 can be limited by the locking groove 62. The
state when the spring plate 61 enters the locking groove 62 through
the protruding structure 60 is shown in FIG. 13.
The sliding component 30 can be locked at the first position or the
second position by entering the locking groove 62 and the releasing
groove 63 through the protruding structure 60 on the spring plate
61, the situation that the sliding component 30 moves back and
forth to affect the connection stability between the detachable
part 20 and the body is prevented, meanwhile, a prompt effect is
realized, for example, when the protruding structure 60 of the
spring plate 61 enters or disengages from the locking groove 62 or
the releasing groove 63, there will be a "click" sound, and the
user will also feel "click" when pushing the sliding component 30,
meaning that the spring plate 61 of the sliding component 30 has
entered/disengaged from the locking groove 62/the releasing groove
63 through the protruding structure 60. After the protruding
structure 60 of spring plate 61 enters the locking groove 62/the
releasing groove 63, the locking groove 62/the releasing groove 63
can limit the movement of the protruding structure 60, and without
the action of an external force, the protruding structure 60 can
not disengage from the locking groove 62/the releasing groove 63.
Meanwhile, in order to ensure that the protruding structure 60 of
the spring plate 61 smoothly enters/disengages from the locking
groove 62/the releasing groove 63, and reduce the frictional force
between the protruding structure 60 and the locking groove 62/the
releasing groove 63, the contact surface between the locking groove
62/the releasing groove 63 and the protruding structure 60 is a
smooth curved surface.

The electrical connector is provided with two hole-shaped
electrical connection portions. The surface of the contact portion
of each electrical connection portion is covered with exposed
copper. The two electrical connection portions are connected with
the positive electrode and the negative electrode of an electrical
signal respectively. The surface of each insertion piece 21 of the
detachable part 20 is plated with metal, such as copper. The
insertion pieces 21 of the detachable part 20 are in contact with
the electrical connection portions when passing through the
electrical connection portions. In this way, positive and negative
signals from the body can be transmitted to the detachable part
20.
Another implementation to achieve electrical connection is,
referring to FIGS. 10-12 and FIG. 14, the casing 11 is further
provided with an electrical connection hole 64. The insertion
pieces 21 of the detachable part 20 include a locking insertion
piece 65 and a conductive insertion piece 66. The sliding component
30 slides from the first position to the second position, the
access hole 31 is opposite to the insertion hole 12, the locking
insertion piece 65 extends into the access hole 31 through the
insertion hole 12, and the conductive insertion piece 66 extends
into the electrical connection hole 64 and is connected with the
electrical connector. In the embodiment of the present application,
the conductive insertion piece 66 comprises but is not limited to:
Pogo pin. Pogo pin is a spring-type probe formed by three basic
components, a pin spindle, a spring and a pin tube through riveting
and pre-compaction with a precise instrument, and a precise spring
structure is disposed inside. When the conductive insertion piece
66 is connected with the electrical connector, the conductive
insertion piece makes contact with the electrical connector through
the pin spindle.
The sliding component 30 slides from the second position to the
first position, and the locking insertion piece 65 enters the
clamping hole 32 from the access hole 31. The position of the
locking insertion piece 65 is locked after the locking insertion
piece 65 enters the clamping hole 32. One implementation is that,
referring to FIG. 15, the locking insertion piece 65 comprises a
first clamping portion 211, a second clamping portion 212 and a
third clamping portion 213 which are coaxially connected to each
other. Specific features can be found in embodiment 2. The features
of the corresponding parts in embodiment 2 and the features in
embodiment 3 can be referred to each other, which will not be
described here.
Referring to FIG. 11 and FIG. 12, in the embodiment of the present
application, the sliding component 30 further comprises a sliding
plate 40 and a shifting pillar 41 disposed on the sliding plate 40.

slide within the sliding grooves 16. The shifting hole 15 is formed
in the position, corresponding to the shifting pillar 41, of the
casing 11, and the shifting pillar 41 can slide within the shifting
hole 15. In use, an external force is applied to the shifting
pillar 41 to make the shifting pillar slide in the shifting hole
15, and the shifting pillar 41 drives the sliding plate 40 to move,
so that the sliding plate 40 slides in the sliding grooves 16
through the side walls.
One implementation is that the shifting pillar 41 comprises a
supporting portion and an operating portion. The shifting pillar 41
is connected with the sliding plate 40 through the supporting
portion. The operating portion extends out of the shifting hole 15
and is bent towards the detachable part 20 so as to be parallel to
the plane where the shifting hole 15 is located. Due to the fact
that the operating portion is parallel to the plane where the
shifting hole 15 is located, a user can use the shifting pillar 41
more conveniently, and the structure of the sliding component 30
and the casing 11 is more compact; meanwhile, the operating portion

groove 63 may be disposed on the outer cover 13 or the inner cover
14, depending on the protruding direction of the protruding
structure 60 on the spring plate 61. The direction of the
protruding structure 60 decides the position of the locking groove
62/the releasing groove 63.
In order to make the structure of the sliding component 30 more
compact, the outer cover 13 is provided with a mounting groove, the
sliding component 30 is disposed in the mounting groove, and the
inner cover 14 covers the mounting groove. The mounting groove can
increase the depth of the mounting cavity, make the structure of
the sliding component 30 compact, and allow the connection between

pillar 67 and the second positioning pillar 68, the outer cover 13
and the inner cover 14 are connected, and the sliding component 30
and the electrical connector can be positioned by the first
positioning pillar 67 and the second positioning pillar 68, so that
the movement of the electrical connector can be prevented. Under
the combined effect of the oblong positioning hole 69, the first
positioning pillar 67, and the second positioning pillar 68, the
sliding component 30 can only move in a certain direction.
The following describes in detail how to mount and dismount the
detachable part 20 and the body.

During dismounting, referring to FIG. 18, the sliding component 30
first slides under an external force from the first position to the
second position in the direction of the arrow in the figure, the
locking insertion piece 65 enters the access hole 31 from the
clamping hole 32, the access hole 31 is opposite to the insertion
hole 12, and the locking insertion piece 65 is pulled out to
separate the conductive insertion piece 66 from the electrical
connector to complete the dismounting process.
The features of the corresponding parts in embodiment 3 and the
features in embodiment 2 can be referred to each other, which will
not be described here.
In the technical solution provided in embodiment 3 of the present
application, the dismounting of the detachable part 20 and the body
is realized through the operation of the sliding component 30. The
insertion pieces 21 can achieve both mechanical connection and
electrical connection, and no connecting wire of the detachable
part 20 is exposed to the outside. The sliding component 30 is
elastic itself, eliminating the need for a spring component. The
angle of the detachable part 20 can be easily adjusted with respect
to the body, so as to facilitate wearing and adjustment for
users.

41 to facilitate the operation.
The limiting portion 722 abuts against the inner side of the top
wall of the groove 74, that is, the top wall of the groove 74
limits the upward movement of the shifting pillar 41 to prevent the
shifting pillar from disengaging from the casing 11; The sliding
plate 40 is located in the groove 74 and is fixedly connected to
the lower side of the limiting portion 722, so that the sliding
plate 40 is fixedly connected to the shifting pillar 41 and moves
under the pressing of the shifting pillar 41, specifically, a
connecting plate is formed on the bottom surface of the limiting
portion 722, and the connecting plate and the top end of the
sliding plate 40 are connected by screws, as shown in FIG. 22. Due
to the fact that the sliding plate 40 is located in the groove 74
in the casing 11, in order to allow the locking insertion piece 65
to be matched with a clamping groove, the insertion hole 12
allowing the locking insertion piece 65 to pass through is
correspondingly formed in the casing 11, as shown in FIG. 21.
In addition, due to the limited thickness of the casing 11, the
pressing portion 721 and the limiting portion 722 are both
elongated and are located at the top surface of the casing 11. In
the present embodiment, the shifting pillar 41 has both the
pressing function and the restricting function, and there is no
need to additionally arrange a limiting portion 722. The structure
is simple and easy to install. Of course, the shifting pillar 41
can also adopt other shifting pillar structures in the prior art,
which may not be specifically limited.
In order to facilitate the installation of the elastic restoration
part 73, in the present embodiment, an elastic restoration part
accommodating groove 75 is further formed in the groove 74. The
bottom end of the elastic restoration part 73 is embedded in the
elastic restoration part accommodating groove 75, and the top end
thereof abuts against the bottom surface of the limiting portion
722. The elastic restoration part 73 can be a spring, a silicone
part and the like, is elastic itself, and can be squeezed into the
elastic restoration part accommodating groove 75 through its own
elastic deformation. Preferably two elastic restoration parts are
disposed at the bottom of the limiting portion 722 to enhance
restoration reliability.
Further, a guide pillar 77 is disposed on the bottom surface of the
limiting portion 722, the elastic restoration part 73 is preferably
a spring and is arranged on the guide pillar 77 in a sleeving mode,
the guide pillar 77 can be integrally formed with the limiting
portion 722 and the pressing portion 721. By arranging the guide
pillar 77, on one hand, the compression and restoration of the
elastic restoration part 73 are guided, and on the other hand, the
restoration reliability of the elastic restoration part 73 is
enhanced, and the pressing reliability of the shifting pillar 41 is
further improved.
In order to ensure that the elastic restoration part 73 is
installed reliably, a silicone sleeve 76 is embedded in the elastic
restoration part accommodating groove 75, and the bottom end of the
elastic restoration part 73 is placed in the silicone sleeve 76.
The silicone sleeve 76 is fixed by interference, that is, the
silicone sleeve is squeezed into the elastic restoration part
accommodating groove 75 through its own elastic deformation, and
fixation is simple and reliable. The bottom end of the elastic
restoration part 73 is embedded in the silicone sleeve 76 and can
be further bonded by strong glue to improve stability.
To lock the position of the locking insertion piece 65 after the
locking insertion piece 65 enters the clamping hole 32, one
implementation is, referring to FIG. 7 or FIG. 15, the locking
insertion piece 65 comprises a first clamping portion 211, a second
clamping portion and a third clamping portion 213 which are
coaxially connected to each other. Specific features can be found
in embodiment 2 and embodiment 3. The features of the corresponding
parts in embodiment 4 and the features in embodiment 2 and
embodiment 3 can be referred to each other, which will not be
described here.
Another implementation is, as shown in FIGS. 21-23, the access hole
31 and the clamping hole 32 form an inverted L-shaped clamping
groove, that is, the inverted L-shaped clamping groove comprises an
upper wide groove body and a lower narrow groove body, and the
locking insertion piece 65 is an L-shaped buckle perpendicular to
the sliding plate 40. Specifically, the sliding plate 40 is affixed
to the side face of the casing 11, and is located below the
shifting pillar 41 in the present embodiment, and when the shifting
pillar 41 conducts downward pressing and upward restoration, the
sliding plate 40 moves up and down with the shifting pillar 41. In
the normal installation state, the locking insertion piece 65 hooks
the sliding plate 40 at the narrow groove body of the clamping
groove to achieve clamping. When the sliding plate 40 moves
downward under the downward pressing of the shifting pillar 41, the
upper wide groove body thereof is made to correspond to the locking
insertion piece 65, the clamping relation between the locking
insertion piece 65 and the clamping groove is lost, and then the
detachable part 20 can be pulled out to achieve detachment. By the
adoption of the clamping groove and the locking insertion piece 65
of the structures, clamping and detachment can be easily achieved
when the sliding plate 40 moves up and down with the shifting
pillar 41, so that the dismounting of the detachable part 20 can be
achieved conveniently.
For the realization of the function of the detachable part 20, the
conductive insertion piece 66 is further disposed on the buckling
part 70. The conductive insertion piece 66 comprises a spring pin
mounting portion 78 and a spring pin 79 mounted on the spring pin
mounting portion 78. Specifically, the sliding plate 40 is
correspondingly provided with a through hole through which the
spring pin 79 passes. The casing 11 is correspondingly provided
with an electrical connector and an electrical connection hole 64
through which the spring pin 79 passes. The electrical connector is
provided with an exposed copper area, and the spring pin 79 is in
contact with the exposed copper area for electrification so as to
realize the function of the detachable part 20.
For the mounting of the buckling part 70 on the detachable part 20,
specifically, a positioning plate 80 is fixedly disposed on the
detachable part 20. The positioning plate 80 locates the buckling
part 70 in the detachable part 20. The positioning plate 80 is
provided with a hollowed-out portion 81 for avoiding the locking
insertion piece 65 and the conductive insertion piece 66. The
mounting process is to press the spring pin 79 into the spring pin
mounting portion 78 through a tool, then mount the buckling part 70
into the detachable part 20, and finally fix the positioning plate
80 on the detachable part 20 by the screw.
In addition, a cover plate 45 is further disposed on the casing 11,
as shown in FIG. 20 and FIG. 21, to be used for covering the
sliding plate 40 and the electrical connector to ensure safety of
use. The cover plate 45 can be buckled onto the casing 11 through a
buckle.
In this embodiment, the host may be a host of a VR device, the
casing 11 is located on a head-mounted support, and specifically is
a part of the head-mounted support, integrally formed with the
head-mounted support, or a separate component, and the detachable
part 20 is an earphone monomer or microphone monomer. Taking the
earphone monomer as an example, in the embodiment of the present
application, the earphone monomer can move in three directions (ie,
when the VR device is worn by the user, the earphone monomer can
move forward and backward, upward and downward and leftward and
rightward relative to the head of the user), and wearing comfort
and versatility are realized, thus achieving easy disassembly on
the premise that three-directional movement of the earphone monomer
is realized.
The mounting and dismounting process of the earphone monomer of the
present embodiment will be described in detail below. The mounting
state of the earphone monomer on the head-mounted support is shown
in FIG. 24, and the locking insertion pieces 65 on the buckling
part 70 (in this embodiment, four locking insertion pieces 65 are
disposed to improve clamping reliability) are clamped in the lower
narrow groove body of the clamping groove in the sliding plate 40,
so as to fix the earphone monomer; When the shifting pillar 41 is
pressed down, the elastic restoration part 73 is compressed and the
sliding plate 40 moves downwards under the guide of the sliding
grooves 16 of the casing 11 until the locking insertion piece 65 is
located in the upper wide groove body of the clamping groove. At
the moment, the locking insertion piece 65 and the sliding plate 40
are disengaged, as shown in FIG. 25, the earphone monomer can be
pulled out according to the existing state to achieve the
dismounting of the earphone monomer, as shown in FIG. 26; When the
earphone monomer is mounted, the shifting pillar 41 is pressed
downward too to make the locking insertion piece 65 correspond to
the upper wide groove body of the clamping groove, and the locking
insertion piece 65 passes through the insertion hole 12 in the
head-mounted support to make the hook portion enter the upper wide
groove body of the clamping groove, at the moment, the shifting
pillar 41 is released to restore, and the locking insertion piece
65 clamps the sliding plate 40 in the lower narrow groove body of
the clamping groove, so as to realize mounting of the earphone
monomer.
